"Mr. Delacour, if there are no problems, let's sign the contract we drew up earlier?"

"Of course, I wish us a prosperous business, Mr. Pente."

Karn shook hands with a middle-aged man, the smiles on both of their faces were very sincere, but the merchant was a bit dreamy to say that he was sincere, just to see who earned it in the end.

The liquidated damages of the contract are also very high, if anyone has the idea of breaking the contract, it is equivalent to making the other party a millionaire in the wizarding world, if you don't want to fulfill the contract or pay compensation, then you can only pay for your life and surname.

The price is too great, except for the kind of dark wizard who is alone, but anyone with a little family business will not do this.

The Dracules not only ran a magical herb farm in France, but also two other industries related to dragon materials, so the Dracules approached Karn to prepare the potion raw materials produced by their family in exchange for dragon materials.

However, Kahn saw the guy's intentions and asked the clone to go to a law firm in London and draw up two contracts full of pitfalls.

"Boss, I feel like Mr. Delacour is a little..."

Keitel's words paused, and she couldn't feel it, but it seemed to have some bad intentions.

Karn said indifferently, "Who cares about them, we just have money to make, Keitel, leave the matter of the shop to the others first, your current task is to talk about the other families that deal in magic materials, and try to get ahead of the breach of contract before it spreads." ”

The Delacour family could still make a little hard-earned money if they were honest in business, but if they weren't right-minded, they were ready to give Karn all their money.

"I see, boss."

Keitel smiled and agreed, feeling that it was the right decision to join her boss; Because of the one-horned sales of fire dragon materials, those who need them have to come to the Karn magic material store to buy them.

But according to the rules of the store, wizards who want to buy fire dragon materials must buy one or two copies of magic materials; At present, the price of potion materials in the store has not increased, but after the stacked potion materials in their store are sold out, other wizards who deal in potion materials will not be able to sell them.

The digestion of the British wizarding world is here, and many wizards do not need to buy potion materials in the short term, and those who operate these people naturally panic; For example, the 'Slug & Giggs Pharmacy' next door to Karn's Potions Ingredients Shop has now transferred the potions materials business to Karn, and they are concentrating on the Potions business.

However, in a few months, Karn will open a potion shop for Keitel in Diagon Alley, and it is unknown if Slug and Giggs will turn into dark wizards and blow up his shop when they see it.

Karn told him again, "I'll leave the rest to you, I still have some business to go back to Hogwarts." ”

"Okay, boss."

Keitel knew that Karn was currently a professor at Hogwarts, but it wasn't clear why he had the time to spend almost every day in Diagon Alley.

Karn didn't go back after leaving the potions shop, he was just a shadow clone, and his body went to the Forbidden Forest to look for unicorns.

In addition to signing a contract with the Delacour and Demiller families, Karn also had to go to Tumbledown Alley, which he hadn't been to since the last time he bought something from Boginbock, and this time he was going to ask Boginbock if he had any way to craft elves.

.........

After the shadow clone was disarmed at his home in Diagon Alley, Chakra and the memories were relayed back to Karn's brain.

At this time, he was using his flying skills to search for the unicorn, and had found a trace the day before yesterday, but was interrupted by a group of centaurs, who fired bows and arrows at him.

The angry Karn taught these magical creatures a good lesson, and although he did not kill them, he made them flee with bruised noses and swollen faces, and scarred bodies; If it weren't for the fact that this was Hogwarts, Karn probably wouldn't have let the person who attacked him go back so easily.

"The goblin craft is really well guarded, and even the dark wizard doesn't dare to take on this kind of business."

Karn took a closer look, and felt that Boginbock hadn't lied to him, and that the elves would rather destroy them than let the human wizards get them in order to protect their craft.

In this case, it can only be made together with the wizard's flying technique, but for the ninja world, there is no difference between the two, but Karn likes it better.

"There are no unicorns found in this area, so it must be that the centaurs have sent a message to the unicorns..."

Karn signaled the area he had searched, and thought suspiciously to himself that the centaurs he had lectured might have a few cautious ones, and if he caught him manifesting, he would not be blamed for being polite.

After searching the area, Karn rushed to Hogwarts with the Flying Charm.

Some time ago, due to the expansion of the greenhouse, Professor Sprout's classes were basically moved back, and she was busy carrying her beloved potion flowers and plants.

But with the end of the greenhouse expansion, Professor Sprout's herbology class had to be replenished, while the other professors were more relaxed, especially Kahn, who had been the busiest in the previous months, and now became the most free.

The seventh-year wizards were busy graduating, and one of them, who was good at herbs and potions, was recommended to Karn to his shop, as he was about to attract a branch and needed a lot of manpower; Sixth-year wizards are busy going to school, and as long as they don't plan to take the S exam, they can easily spend the final year.

The fifth-year wizard also had to prepare for the exam, and Karn knew that the .l exam didn't require a duel, so he wrote a letter to Lupin with two hundred Galleons and asked him to compile a list of exam points and send it over.

When the fifth-year wizards got the exam preparation materials that Karn had given them, they were all cheering, although it was more than ten years ago, the Ministry of Magic hadn't changed the content of the exam on a large scale for a long time, so the preparation materials Karn gave them were still very useful.

However, there were some bold schoolgirls who wanted to take advantage of the opportunity to come up and offer kisses, which seemed to be organized and premeditated, but were still prevented by Karn's swift reaction with a barrier charm.

If one or two are pretty, forget it, a group of people get together, it's just scary.

The remaining Defence Against the Dark Arts classes from Year 1 to Year 4 were more relaxed, and those who memorized Karn's knowledge in class and then performed well in the final dueling class could get full marks from him.

After returning to Hogwarts from the Forbidden Forest, students on the road would greet Karn when they saw him.

"Professor!"

"Professor Pente."

Karn would also reply to such students, who had always been elusive when there were no classes, and this had spread among the students, and only Hermione could see Professor Pentt regularly.

It is said that it was someone who gave Professor Pentt a strange gift, which caused Professor Burnt to hide out often; Although there is no specific confirmation, the news is clear, and many people are very sure that someone boldly gave Professor Pent the clothes he wore will make the professor often not come back.

Karn didn't know much about it, no one would ask him that in class, and when it came to class, the only one who could talk to him was Hermione.

Today is another day when no unicorn has been found.

Karn returned to the Defence Against the Dark Arts professor's office and found that the door was unlocked.

"Hermione?"

Karn pushed the door open and looked in, and saw the smell of potions coming from the room, and the cauldron was still brewing, but there was no one in the seat; He told Hermione that he could use the office as he pleased, so Hermione often came here to make potions.

"Probably to the bathroom?"

Karn glanced at the cauldron and wanted to use the potion for a moment, but he didn't know much about potions and could only judge from the descriptions in the book, but the potion had a peach flavor, so he didn't dare to say for sure.

It is best not to touch the potion during the brewing process, and Hermione will probably leave after arranging it.

As he sat down in his seat, Karn suddenly remembered that he hadn't tormented Tom in a long time, and suddenly wanted to take it out and burn it with a fierce fire, after all, he had bad intentions.

However, just as Karn was about to look for the diary, he suddenly found that the diary had been taken.

"Where's the diary... Hermione took it? ”

It was difficult for anyone other than Hermione to get into her office, and among the students below the fifth grade, Hermione should have been the only one who had learned to deal with the anti-lockpicking spell, but she should have known that it was a dark magic item.

"Professor Pente."

"Something's wrong."

Harry and Ron suddenly ran to Karn's office door, and one of them spoke to him breathlessly.

Karn asked directly, "I see, where is Hermione?" ”

"Hermione? What does it have to do with her, it's Gryffindor's fifth-year seniors who have an accident. ”

Harry looked puzzled, and then said quickly, "Just near the Gryffindor Tower, that senior sister was attacked, as if she had been hit by a very powerful petrification charm. ”

"Ron, you go back and wait for news, Harry, you come with me."

Karn cast a levitation following spell directly on Harry, and then used the Flying Charm himself to go straight to the girls' bathroom on the second floor.

A minute later, Harry also shouted and floated over, landed on the ground and looked left and right, and said, "Professor, this is the girls' bathroom." ”

Karn pointed to the sink and said to Harry, "I know, now use your old snake tongue to open this sink." ”

"Open..."

"You're speaking English, Harry."

Karn sighed, but remembered that Harry's snake was due to Voldemort's soul fragment, and he might not be able to say it when he was nervous, so he used an oolong to get out of the hole in front of Harry.

A black snake appeared in front of Harry's eyes, causing him to switch from English to snake talk, but he always said 'Stand back, stand back.' ’

"Harry, it's fake, you say open it now, and the black snake is gone."

"Open!"

This time Harry was talking in the old snake voice, and when the washstand heard Harry's words, it instantly cracked left and right, revealing a passage to the secret room.

"Go back now, Harry, and you'll be fine in a moment."

With that, Karn used the Flying Charm to enter the chamber directly.

"Professor, I'm a snake boss..."

Harry wanted to go down with Karn, he thought that this incident must be terrible, and there would be no danger if he followed Professor Pente, but Professor Pent flew straight in, and he didn't intend to take him.

Harry looked over and saw that it was pitch black underneath the passageway, and he didn't know how high it was, and he didn't have a wand with him.

"It's better to inform Professor Dumbledore..."

After convincing himself, Harry immediately got up and ran towards the bathroom.
